I am generating a custom edit page using an xslt file/transform and in the xslt, I have a RadEditor. Because the RadEditor is in the xslt file, I do not have access to the normal RadEditor methods to get the html content on postback.  Basically, I have to get the content via Request.Form.  Also, the content will be stored as an attribute value in xml, which means it needs to be encoded since I obviously can't store symbols like < & >.

The content that I get back from Request.Form looks like it has been encoded (ie: < symbol replaced by '%3c') and I can store everything fine in the xml db.  However, when I retrieve the data, I don't have any way of decoding it so it displays correctly in the RadEditor.

Any ideas on what I can do with the encoded data coming back from the db?

Hi Erick,

We use the code below to encode the the special tags and symbols in HTML content:

internal class ContentEncoder 
      { 
            static ContentEncoder() 
            { 
                  _characters = new char[] {'%', '<', '>', '!', '"', '#', '$', '&', '\'', '(', ')', ',', ':', 
                                                       ';', '=', '?', '[', '\\', ']', '^', '`', '{', '|', '}', '~', '+'};
                  _characterBytes = Encoding.ASCII.GetBytes(_characters);
            }

            private static char[] _characters;
            private static byte[] _characterBytes;
            public static string Encode(string text)
            {
                  for (int i=0; i<_characterBytes.Length; i++)
                  {
                        text = text.Replace(_characters[i].ToString(), "%" + _characterBytes[i].ToString("x"));
                  }

                  return text;
            }

            public static string Decode(string text)
            {
                  for (int i=_characterBytes.Length - 1; i>=0; i--)
                  {
                        text = text.Replace("%" + _characterBytes[i].ToString("x"), _characters[i].ToString()); 
                  } 
 
                  return text; 
            } 
      } 
 

Our suggestion is to integrate the code above in your CMS to achieve your scenario.

This code works well; I am also pulling the editor content from the request.form() collection.

I'm curious if there is any other server side code that I might be missing when I don't call the edit control content, such as security filters or anything like that?

Hi Christopher,

All editor's filters run on the client. If you want to obtain the editor's content parsed and validated by the filters, you should set the "true" parameter to the editor.get_html() method, e.g.

editor.get_html(true);
